Kilts in England

Hi all,
I'm new to this site and to planning our wedding!
My FiancÚ is Scottish and really wants to wear a kilt on his Wedding day.
We live in Southern England and apart from his Brother the entire bridal party is English, and no one owns a kilt.
He wants to wear McEwan Tartan and have his Groomsmen in the same. However we cannot find anywhere yet to hire it. Any suggestions?

Our back up plan is to buy him a kilt and hire outfits for the other boys. But what would work better, suits with McEwan ties etc or kilts of their choice?

My Dad is English is it ok for him to wear a suit or should he wear a kilt. He's actually happy either way.
